Here you can find a list of the files and down-loads you will need for the setup of the bridge. If you have one of the mentioned files or packages on your distribution, of course there is no need to create network load.

I'll only mention the files for the 2.2.14 kernel. If you want to try a different one (e.g. 2.2.15 or the recent development kernel) just replace the kernel version number and look whether you find it.

Important: You have read the abstract, didn't you? So you know that there is no need to download any kernel-patch if you're working with a kernel later than 2.3.47.

File and package list

Unpatched kernel-sources

E.g. linux-2.2.14.tar.bz2 available from your local kernel.org mirror. Please check first if you find it in your distribution (take unpatched kernel-sources). If you don't, please check The Linux Kernel Archive Mirror System for a close by mirror and down-load it from there.

Bridge patches

Note: If your kernel is later than 2.3.47 you don't need this. The bridging is part of the mainstream from that version.

Note: There are also patches allowing to work with IP chains. I never tried it, for I don't see the need to fire-wall inside my LAN, and absolutely no need to bridge against the outer world. Feel free to contribute about that issue.

Kernel patches for the stable 2.2 kernel.

Available Kernel patches

bridge-0.0.9-against-2.2.18.diff, the main kernel patch against 2.2.18

Now it's time we configure our freshly patched kernel to create the ability to bridge.

Run make config, make menuconfig or the click-o-ramamake xconfig. Select bridging in the networking option section to be compiled as a module. AFAIK there is no strong reason why not to compile it as a kernel module, whereas I heard rumors about problems with compiling the bridging code directly into the kernel.

Compile your kernel Example 2. Make the new compiled kernel-image to be loaded. I don't know if the kernel patches only apply to the bridging-module or also modify some interfaces inside vmlinuz. So it might not be a error to give a reboot after you updated the kernel-image.

After the compilation shown in Example 3 have worked properly, you can copy the executables to let's say /usr/local/sbin/ (at least I did). So the commands you have to give should be clear, but to be complete see Example 4
